Abstract
Atrial and ventricular action potential gradients at phase 0 upstroke initiate propagating wave fronts during cardiac excitation that generate sequentially the P and QRS waves of the electrocardiogram (ECG). Ventricular excitation follows atrial excitation after a delay in the atrioventricular (AV) node and conduction time through the His-Purkinje network. This delay permits completion of atrial contraction and ventricular filling before ventricular contraction.
